Simplifying Infectious Disease Testing with Saletto’s Safe and Comfortable Collection​


Saletto® Saliva Collection Device

Tailored for Infectious Disease Testing Applications

In the battle against the global COVID-19 pandemic, the need for safe, convenient, efficient, and non-invasive testing has never been greater. Enter the Saletto Saliva Collection Device, initially designed with infectious disease testing in mind, specifically tailored to address the urgent demand for COVID testing. This innovative device has rewritten the playbook on sample collection, offering a simple and comfortable way for individuals to provide saliva samples and a contained collection method for safety during assisted collection. By eliminating the discomfort and complexity associated with traditional swab-based methods, Saletto has played a pivotal role in expanding access to testing, enhancing the reliability of results, saving time and resources and ultimately contributing to the fight against the pandemic. In this new era of diagnostics, Saletto stands as a testament to the power of technology to drive positive change in healthcare and infectious disease management.​​

According to COVID-19 performance studies conducted, Saletto® proves comparable to competitor devices, with a positive percent agreement or sensitivity of 95.5% and negative percent agreement or specificity of 95.4%.

Enhancing Accessibility and Patient Compliance​

Saletto® prioritizes user experience and inclusivity.

  • Designed for all ages and abilities, enabling independent or caregiver-assisted collection.
  • Alleviates test hesitancy caused by needle fear or discomfort by incorporating a soft collection sponge for user comfort.​
  • The non-invasive, comfortable nature of Saletto promotes higher testing compliance (92% for home saliva tests vs. 60% for clinic nasal swabs).​

Streamlines Infectious Disease Testing Workflows

Saletto seamlessly integrates into and simplifies testing workflows to save valuable resources, time, and cost, providing quicker results.​

  • Enables convenient at-home testing, saving time and resources for labs and clinics.​
  • Reduces sample preparation steps, providing high-quality saliva samples with significantly reduced viscosity (83% reduction), minimized variation (97% reduction), and unwanted particles. In high viscosity donors, passive drool saliva samples exhibited an average viscosity of 7.70 cP, while Saletto®-filtered samples averaged only 1.29 cP. (Download White Paper on Reduction of Saliva Viscosity with Saletto)​
  • The Collection Vial, a centrifuge tube, streamlines sample preparation by eliminating the need for sample transfer. We offer customizable adapters tailored to specific customer needs, facilitating seamless sample preparation and transfer in laboratory settings.​

Allows for Confident Collection​

The users can trust the product and the labs can trust the process​​

  • For the user:  Built-in sample sufficiency Indicator turns blue to signal saturation of the collection Sponge and completion of collection. ​
  • For the lab or diagnostic firm: Proven efficacy for downstream testing techniques.​
  • For assisted collection: enables safe collection by containing oral fluid and eliminating exposed sample transfer. ​

Easy 3-Step Process

Step 1: Collect

The intelligent design makes it simple to collect, prepare and transfer saliva. The user moves Saliva into the Sponge in their mouth until the Sample Sufficiency Indicator alerts them that the sponge is fully saturated​.

Step 2: Compress

Once collection is complete, the Push Cap is used to compress the sponge till the saliva reaches the Fill Line. Clean saliva is safely transferred into the Vial.

Step 3: Cap

The Handle is then ready to be discarded and the Vial capped to mix the contents.

Absorbent Sponge for Mess-free Collection​

The Saletto Saliva Collection Device represents a significant advancement in infectious disease testing. Designed to simplify the process of saliva sample collection and provide comfort to the user, it features a highly absorbent sponge for quick and mess-free collection. ​

Integrated Filtration Technology for Easier Handling

Integrated filtration technology removes impurities and reduces sample viscosity, making handling easier. A sample sufficiency indicator ensures precise collection, while ambient temperature transport and sample stability add to its practicality. Explore how the Saletto Saliva Collection Device is transforming the landscape of infectious disease management for laboratories, researchers, and healthcare professionals.
